Solving the Uncertainty Management Puzzle
As shipping companies continue to make their operations more cost efficient and environmentally friendly, the demand for high density data has increased. Uncertainty management is...
Survey boats are in various sizes. Small survey boats (<15m) facilitate work in challenging envirionments like shallow or confined waters. The survey vessels are flexible and transportable - sometimes even on a trailer. They also have their limitations and requirements and the survey results may need more attention as smaller boats may be more sensitive to heave, pitch and roll. This theme focuses on aspects and experiences when working with small survey boats.

Following the suspension of Parliament in the summer of 1858 due to the ‘Great Stink’, an act was passed to allow construction of a network of giant sewers, pumping sta...
Every month we will focus on a specific theme, featuring a selection of articles which have previously been published in Hydro International magazine. to present a complete recap of the subject. If you don't want to miss these themed recaps, sign up for the newsletter (sign up here).
In times past, it was often the lot of the hydrographer and ocean scientist to have hand-me-down ships and vessels from the naval service or revenue service of various nations. Or,...
High-resolution bathymetry and water quality surveys of shallow shelf and inland water bodies are an increasingly necessary part of environmental management with climate change pre...
Recent hydrographic advances are revolutionising the way the marine environment can be accessed, scanned and quantified. With the emergence of sonar technology and, more recently,...
Remote, difficult to access: it just depends on the point of view. Often, trying to reach some areas with a classical survey vessel or with an opportunity launch is like banging ou...
Seaports, waterways and climate are inextricably linked. Weather anomalies change bottom contours and destroy aids to navigation, compromising safety. In the past decade, maritime...
During the last week of a hydrographic survey of Lough Derg, Ireland’s third largest lake, the remnants of a preserved flooded landscape were unveiled beneath the surface wit...
A major part of Paraguay River’s sounding and signalling is maintained by the Brazilian Navy. Trying to stay abreast of the state of the art on inland hydrography and cartogr...
An earthquake of unprecedented magnitude hit the east coast of Japan on 11 March 2011. A tsunami, a large wave caused by the earthquake, crashed into the ports and coastal regions,...
Most continents have long histories of utilising their waterways to facilitate trade but, with a few notable exceptions, Africa has not yet taken full advantage of possible riverin...
Survey efforts in shallow water present a challenge; when coupled with protected species and critical habitat such as coral reefs, they can prove impossible. Tetra Tech, in conjunc...
